Description

Technical Field

[0001] The present invention relates to the technical field of corrugated sheet welding equipment, and in particular to intelligent spot welding equipment and technology for wide-width corrugated sheets. Background Art

[0002] The corrugated sheet is a sheet material with a corrugated shape, which has the characteristics of a large surface area. Based on this characteristic, the corrugated sheet has good heat dissipation performance, so it is often used to prepare a box with heat dissipation requirements, such as a corrugated oil tank. However, the shape of the corrugated sheet will also reduce its strength and be easy to deform. Therefore, during processing, it is necessary to weld reinforcing ribs on the corrugated sheet to increase its strength. Spot welding is generally used as the welding method. Spot welding refers to a welding method that uses a columnar electrode to form a welding spot between the contact surfaces of two overlapping workpieces during welding. During spot welding, pressure is first applied to make the workpieces in close contact, and then the current is turned on. The contact part of the workpiece melts under the action of resistance heat, and welding can be performed. For example, the Chinese utility model patent with the authorization announcement number CN212094953U discloses a corrugated sheet reinforcement rib spot welding machine, including two support plates and two side plates. The front left side of the support plate on the front side is connected to a first servo motor by screws, and a rotating shaft is rotatably connected between the two support plates. However, the current spot welding equipment has the following defects when welding corrugated sheets:

[0003] When current welding equipment is used for welding at the melting point, the welding rod directly contacts the melting point to form a weld, which cannot be moved in a small stroke and cannot be compared with the weld pattern formed by manual spot welding. The welding area is small and the welding quality is poor. In addition, due to the special shape of the corrugated sheet, its strength is relatively poor. After it is fixed, when the reinforcing ribs are tightened, it is easy to cause deformation at the high bend of the corrugated sheet, especially for wide corrugated sheets, which are more prone to deformation, resulting in deformation of the corrugated sheet after welding.

[0004] To this end, we propose a wide-width corrugated sheet intelligent spot welding equipment and process to solve the above problems. Summary of the invention

[0049] Step 1: Place the corrugated sheet on the surface of the fixed table 21 on the fixed assembly 2, and the two first cylinders 29 drive the sliding plate 26 to move, and use the clamping blocks 27 to clamp the two sides of the corrugated sheet, and make the highest point of the corrugated sheet be located directly above the part of the top plate 23. After the corrugated sheet is clamped, the part of the top plate 23 corresponding to the highest point of the corrugated sheet moves up under the action of the third cylinder 215, and the top bar 24 is used to support the bottom of the highest point of the column corrugated sheet, and at the same time, the second cylinder 214 drives the lower electrode column 211 to move up and contact the corrugated sheet;

[0050] Step 2: Place the reinforcing rib on the corrugated sheet at the position where welding is required, then the three-axis moving assembly 3 drives the welding head assembly 4 to move to one side of the reinforcing rib, fix the welding rod on the welding rod fixing head 49 on the welding head assembly 4, then the carrying block 54 in the pressing assembly 5 moves to the position just above the reinforcing rib, then the fourth cylinder 55 drives the pressing rod 56 to move downward, and the pressing column 57 is used to press the top surface of the reinforcing rib, and the upper electrode 58 contacts the reinforcing rib;

[0051] Step three: The capacitor module 11 is started, and the temperature at the contact point between the corrugated sheet and the reinforcement rib rises to form a melting point. The three-axis moving component 3 drives the welding head component 4 to move to the melting point position for welding. During welding, the first micro cylinder 410 and the second micro cylinder 412 drive the welding rod to move in a contour to form a weld mark at the welding point. After welding is completed, step two is repeated to place a new reinforcement rib, and multiple reinforcement ribs are welded in sequence. During welding, the welding rod moves in a contour to form a weld mark, thereby increasing the area of ​​the welding point.

[0052] Embodiment 4:

[0053] See also Figure 1-9 , which is the fourth embodiment of the present invention. This embodiment is based on the above three embodiments. When the present invention is used, the corrugated sheet is placed on the surface of the fixed table 21 on the fixed component 2, and the two first cylinders 29 drive the sliding plate 26 to move, and the clamping blocks 27 are used to clamp the two sides of the corrugated sheet, and the highest point of the corrugated sheet is located directly above the part of the top plate 23. After the corrugated sheet is clamped, the part of the top plate 23 corresponding to the highest point of the corrugated sheet moves up under the action of the third cylinder 215, and the top bar 24 is used to support the bottom of the highest point of the corrugated sheet. , and at the same time, the second cylinder 214 drives the lower electrode column 211 to move up and contact the corrugated sheet; the reinforcing rib is placed at the position where welding is required on the corrugated sheet, and then the three-axis moving assembly 3 drives the welding head assembly 4 to move to the side of the reinforcing rib, and fixes the welding rod on the welding rod fixing head 49 on the welding head assembly 4, and then the carrying block 54 in the pressing assembly 5 moves to the position just above the reinforcing rib, and then the fourth cylinder 55 drives the pressing rod 56 to move down, and the pressing column 57 is used to press the top surface of the reinforcing rib, and the upper electrode 58 contacts the reinforcing rib; the capacitor module 11 starts The temperature at the contact point between the corrugated sheet and the reinforcing rib rises to form a melting point. The three-axis moving assembly 3 drives the welding head assembly 4 to move to the melting point position for welding. During welding, the first micro-cylinder 410 and the second micro-cylinder 412 drive the welding rod to move in a contoured manner to form a welding mark at the welding point. After welding is completed, step 2 is repeated to place a new reinforcing rib and weld multiple reinforcing ribs in sequence. When welding, the welding head assembly 4 of the present invention adjusts the angle through the rotating block 42, and the first dovetail opening 44 and the second dovetail opening 46 are on the vertical plane of the angle. A micro cylinder 410 and a second micro cylinder 412 can drive the electrode fixing head 49 to move in two axes on the surface, and can perform contour movement at the melting point to form a weld mark. Compared with the welding of the welding spot, the welding area is larger, closer to manual welding, and the welding quality is higher. The fixing component 2 of the present invention is used to fix the corrugated sheet. After fixation, the top plate 23 rises through the top bar 24 to support the bottom of the high position of the corrugated sheet to form a support, thereby avoiding deformation of the corrugated sheet when the reinforcing ribs are pressed down, and is more suitable for spot welding of wide corrugated sheets.
